PIZZA HUT Delivery is spending £20million on ramping up its delivery operations as more customers order their takeaways using smartphones.

The firm, owned by US group Yum!, said the money will be spent on increasing its UK store numbers by 100 to 400 creating 2,000 new jobs. It has a long-term aim of having 700 stores.

Managing director Mark Fox said the "aggressive" expansion plan will include boosting its online technology services to allow customers using new superfast 4G mobile phones to make orders. It will also look to refresh its menu with more innovative products. "We are committed to driving the visibility of Pizza Hut Delivery," said Fox.

The delivery business is distinct from Pizza Hut dine-in restaurants which were sold to private equity firm Rutland Partners last month.
